Calibrachoa plant named ‘Balcaboldel’

ABSTRACT

A new and distinct cultivar of Calibrachoa plant named ‘Balcaboldel’, characterized by its deep yellow-colored flowers, medium green-colored foliage, and moderately vigorous, mounded-trailing growth habit, is disclosed.

Latin name of genus and species of plant claimed: Calibrachoa x hybrida.

Variety denomination: ‘Balcaboldel’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofCalibrachoa plant botanically known as Calibrachoa x hybrida andhereinafter referred to by the cultivar name ‘Balcaboldel’.

The new cultivar originated in a controlled breeding program in ArroyoGrande, Calif. during June 2013. The objective of the breeding programwas the development of Calibrachoa cultivars with attractive flowercoloration, and a moderately vigorous, mounded-trailing growth habit.

The new Calibrachoa cultivar is the result of cross-pollination. Thefemale (seed) parent of the new cultivar is CALIPETITE Yellow‘SAKCAL107’, U.S. Plant Pat. No. 24,382, characterized by its mediumyellow-colored flowers, medium green-colored foliage, low growth vigorand compact-mounded growth habit. The male (pollen) parent of the newcultivar is the proprietary Calibrachoa x hybrida breeding selectioncoded 9389-3, not patented, characterized by its medium yellow-coloredflowers having red midveins, medium green-colored foliage, low growthvigor and compact-mounded growth habit. The new cultivar was discoveredand selected as a single flowering plant within the progeny of the abovestated cross-pollination during March 2014 in a controlled environmentin Arroyo Grande, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings sinceMarch 2014 in Arroyo Grande, Calif. and West Chicago, Ill. hasdemonstrated that the new cultivar reproduces true to type with all ofthe characteristics, as herein described, firmly fixed and retainedthrough successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedlyobserved and can be used to distinguish ‘Balcaboldel’ as a new anddistinct cultivar of Calibrachoa plant:

-   -   1. Deep yellow-colored flowers;    -   2. Medium green-colored foliage; and    -   3. Moderately vigorous, mounded-trailing growth habit.

Plants of the new cultivar differ from plants of the female and maleparents primarily in having more growth vigor. In addition, plants ofthe new cultivar differ from plants of the male parent in not havingred-colored midveins.

Of the many commercially available Calibrachoa cultivars, the mostsimilar in comparison to the new cultivar is SUPERBELLS Yellow Improved‘Balcal1004’ U.S. Plant patent application Ser. No. 15/530,702. However,in side by side comparisons, plants of the new cultivar differ fromplants of ‘Balcal1004’ in at least the following characteristics:

-   -   1. Plants of the new cultivar have a flower color that is        slightly different from plants of ‘Balcal1004’;    -   2. Plants of the new cultivar have fewer flowers per plant than        plants of ‘Balcal1004’; and    -   3. Plants of the new cultivar have slightly larger diameter        flowers than plants of ‘Balcal1004’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonablypossible to make the same in color illustrations of this type, typicalflower and foliage characteristics of the new cultivar. Colors in thephotographs differ slightly from the color values cited in the detaileddescription, which accurately describes the colors of ‘Balcaboldel’. Theplants were grown in 4-inch pots for 6 weeks in a greenhouse in WestChicago, Ill. Plants were given one pinch one week after transplant.

FIG. 2 illustrates a close-up view of an individual flower of‘Balcaboldel’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmentalconditions to date. Accordingly, it is possible that the phenotype mayvary somewhat with variations in the environment, such as temperature,light intensity, and day length, without, however, any variance ingenotype.

The chart used in the identification of colors described herein is TheR.H.S. Colour Chart of The Royal Horticultural Society, London, England,2015 edition, except where general color terms of ordinary significanceare used. The color values were determined in November 2017 undernatural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants producedfrom cuttings from stock plants and grown in a glass-covered greenhouseunder conditions comparable to those used in commercial practice. Theplants were grown in West Chicago, Ill. in 4-inch pots for 7 weeksutilizing a soilless growth medium. Plants were given one pinch one weekafter transplant. Greenhouse temperatures were maintained atapproximately 68° F. to 72° F. (20° C. to 22° C.) during the day andapproximately 64° F. to 66° F. (18° C. to 19° C.) during the night.Supplemental lighting was used. Measurements and numerical valuesrepresent averages of typical plants.
